7 Claims. l

This invention relates to sliding windows, and has Vfor its object toprovide a sliding window assemblage, more particularly, but of course,not exclusively, for use on shipboard, the window whereof may be readilyraised or lowered by means of hand. pressure alone, is automaticallyrendered watertight after movement without the aid oi extraneous handscrews, or the like, and which, being of simple and robust construction,is relatively cheap to produce.

According to our invention, a sliding windowv assemblage comprises aframe `adapted for tting to a window aperture, and a counterbalancedsheet of glass or other appropriate material (hereinafter, forconvenience of reference only, designated glass) associated with saidframe and adapted to be raised or lowered by hand into and out ofaperture-closing position, and said assemblage being characterised inthat the combined weight of said glass and the means where by it iscounterbalanced is utilized to effect, auto matically, the watertightseating or sealing and locking of said glass (after movement thereof)against the adjacent frame or frame portion. Our invention is furthercharacterised in that seating or sealing and locking of said glass maybe effected in any position of vertical adjust'- ment in which the glassmay be placed.

in one embodiment, our invention comprises a frame to each side whereofis pivotally secured, by means of t'wo or more parallel links orshackles, a vertical housing; a pair of rack bars slidably located ineach housing and in opposed engage ment with a pinion positionedtherebetween and rotatably journalled in said housing; and a sheet ofglass secured adjacent its edges to a rack bar of each housing, theco-operating rack bars being provided with individual balance weights,or alternatively a single weight common to both.

One or more oi the links or shackles is or are provided with a toothedquadrant in engagement with a hand-operable pinion, whereby the vglassand counterbalancing mechanism is pivoted about said shackles away fromthe frame to permit ready adjustment of said window by hand.

We will further describe our invention with the aid of the accompanyingsheets of eiiplaiiartory drawings which illustrate, by lway of ex'-ample only, and not of limitation, one inode of embodying same.

In said drawings, in which like characters of reference denote likeparts wherever they occur,

Fig. 1 is a front elevation of a window assemblage suitable for Ause `onshipboard,

Fig. 2 is a side elevation,

Fig. 3 is a section drawn to an enlarged scale as compared with thepreceding views, taken as on line A-A, Fig. l,

Fig. 4 is a section of a rack bar housing, taken as on line B-B, Fig. 2,and drawn to an enlarged scale as compared with Fig. 3; and

Fig. 5 is a fragmentary elevation in part section.

Referring now to said drawings, I denotes a metal frame with securingbolt holes 2 and a spigot portion 3 adapted to enter the Window apertureci a ships plating. Pivoted at each side of frame I on pins il, 4 aretwo connecting links 5, 5X which carry at their outer ends, means ofcranked pins t, t, a vertical housing t; said cranked pins 6, 6 permitadjustment of the eiective length of links 5, 5x. Pins t are adjustablylocated at one end within bifurcated end portions 5e of links 5, tx bymeans of screws 5b, and. are provided with medial ats Kia whereby theymay be turned to required positions of adjustment with the aid of anappropriate spanner. Links, 5, 5X are therefore capable oi being readilyadjusted to permit the iitting of glass, and/'or resilient seatingtherefore, of various thicknesses. The other ends oi said pins ii arerevolubly located in apertures provided for their reception in housingl', and thus said housing l is permitted a limited amount of arcuatemovement at the end of links 5, 5X, and conse quently toward, or awayfrom frame i, while maintaining its parallel relationship therewith.

Slide-bly located within each housing l are a pair of rack-bars t, it inopposed engagement with a pinion li free to rotate about a spindle I2 onball races I3, I3. Said spindle i2 is secured within housing 'i by meansof an enlarged head portion ia and a screw i213. A sheet of glass it,provided with ahandle I5, is secured in any convenient manner to rackbars 9, and a weight 8 is bolted to the lower extremities ofco-operating rack bars lil, i5 in order to counterbalance the weight ofrack bars 9, S! and attached glass I4. The rack-bar housings 'l andthepinions ll are preferably formed of Bakalised linen, or synthetic resinboard, in order that the movement may be self -lubrica'ting The twolower links 5X, 5X are each provided with a toothed quandrant Yand inoperative engagement with Said quadrants are pinions I6, Iii, keyed to ashaft Il journalled in side brackets la, la of frame I. The length ofshaft li may be adjusted by means of a pin-and-slee've joint I8.

One end I'Ia of shaft I'I is entered into a gear ture closing position.

box I9 secured to a bracket extension I b of frame I, and securedthereto is a bevel wheel 20 arranged to mesh with a pinion 2l secured toa spindle 22 which, being disposed at right angles to shaft Il, isjournalled at each end in bushings I9EL screwed into the sides of gearbox i9. An end 22a of spindle 22 projects exteriorly of gear box I9 andis adapted to be engaged by a handle 23 whereby pinion 2i, bevel wheel2t, and so shaft Il is rotated. Other types of gearing may, of course,be utilized in place ci that described, and may be disposed on eitherside of frame I as desired: in some instances gearing may be omitted andsuitable toggle or other linkage substituted therefor, or, handle 23 maybe secured directly to shaft Il.

Normally, the combined weight of the counterbalanced assembly carried atthe ends of links X, 5, 5X, causes glass it to bear against a sealingstrip 2li of rubber, or other suitable resilient material, which isfitted around the window aperture of frame l, and, when the glass is inalowered position, against vertical rubber seating strips 25 secured toframe I below the window aperture. Thus, an all round watertight jointis attained between glass and frame when the window is closed i. e. whenglass le is in its uppermost position; and when said glass is partiallyor fully lowered, a watertight joint is still maintained between saidglass and the adjacent portions of sealing strip 211;.

The abutment of glass It against strips 2e and 25 effectively preventsthe raising or lowering of said glass until the assembly carried bylinks 5, 5X, 5, 5X is pivoted upward and so away from frame I. Thislatter operation is achieved by turning the handle 23 (as indicated byarrow in Fig. l) when pinions I 5 on shaft il are rotated to movetoothed quadrants 5, 5C of links 5K, x upward. Housings l', l are thuspivoted upwards and glass it moves clear of sealing strips 24 and 25,and while in this latter state the position of glass Ill in relation tothe window aperture may be readily changed by appropriate nnger-tippressure on handle I5.

When frame I is fitted to a ships platingbeing secured thereto inwatertight manner by bolts passed through apertures 2-the weight ofhousings 7, "l, and associated parts being supported by links 5, 5X, 5,5X, causes the glass It (assuming it to be in its uppermost position) topress firmly against the rubber sealing strip 2i., thus forming awatertight joint and erectively sealing the window aperture, andautomatically locking the glass in position. If it is desired to openthe window, handle 23 is turned, thus rotating-through pinion 2! bevelwheel 25.3 and shaft i-the two co-acting pinions I5, which cooperatewith quadrants 5 of links 5X to move glass Ill out of sealing abutmentwith strip 2li. It is to be noted that when released handle 23 willautomatically return to its original position, and-by reason of theweight of housings l and associated parts acting on quadrants 5 and sopinions IB--the glass ld is locked in its new position.

To limit the upward travel of glass Id a rubber or other stop 26 issecured adjacent to the top of frame I as illustrated, and to limitupward movement of weight 8 and so downward movement of glass It, arubber stop 2 is provided on the upper edge of the weight 8. Strips 25positioned on either side of frame I ensure a parallel seating for glassI4 when it is in other than aper- With the object of preventing waterpassing between housing 'I and the adjacent sides of frame I when thewindow is partially or fully opened, angle strips 28 are secured-as byscrews 22S-around the perimeter of frame I, and which strips are adaptedto guide water seepage, into a conventional drip tray (not shown) fittedbelow the window and so outboard of the ship.

As said hand-lever is positioned on the inside of the window,unauthorized opening of same from the outside cannot be effected.

In an alternative method of securing the window assembly to the mainframe, the pivotal shackles may be replaced by upwardly inclined andslotted members immovably secured to said main frame. Appropriatelyspaced pins fitted on either side of the rack and pinion housings areentered in said slots, and the inclinations thereof and the weight ofthe window and control mechanism effect the required water-tightness ofthe window.

The clearance necessary to raise or lower the window may be obtained inthis instance, say, by lever-actuated cams adapted to urge the assemblyupward, and therefore away, from the sealing material.

in a further embodiment, the rack and pinion gearing may be replaced bydouble-cut right and left hand screw-threaded rods of coarse pitch whichcause a balancing weight or weights associated with nuts working on saidrod to be moved in a direction opposite to that of the window as thelatter is raised or lowered.

It will be apparent that windows constructed according to our inventionmay be utilized with advantage in all circumstances where slidingwindows are required, and that the construction and arrangement ofcomponent parts may be varied without departing from the scope of theinvention.
